Jalalabad, Afghanistan ? Militants detonated a roadside bomb Thursday, killing a man and his grandson selling vegetables in eastern Afghanistan.

The blast went off in Jalalabad while Lt. Gen. Karl Eikenberry – the top U.S. general in Afghanistan – visited a U.S. base in the city, but he apparently was not the target.

Eikenberry, who visited American troops hunting terrorists and leading reconstruction projects, also stopped at the Jalalabad hospital where five people wounded in the blast were taken.
